there are some reasons, one is they just can't do it because they don't have the skills, another is that it's just not worth it because most people put quantity before quality. you can even see this in the comments here.
Well, if I would look at the images in an art gallery etc. yeah, quality before quantity. In a porn VN, well, most here could jerk off on some stick figures if it's a hot situation

. In a porn VN, I personally, don't spend too much time on single images and if there is finally the one I spend a bit longer

I do not admire the perfect scenery, the rich details placed on a cupboard, the perfect lighting etc.. Hot protagonist, hot situation. Sadly, Stopers claim is not to deliver a porn VN but amazingly rendered images with sexual content which you can "play" like other ren'py games.
So maybe people get this one day, JOHN is about stunning quality of every single image and not creating a porn VN with regular output of updates. His patreons are fine with it, otherwise he wouldn't have any. So be lucky to get from time to time a new update "for free" here and jerk off on some other stuff before the complains of horny pirates annoy me.
